With DNP's unique connection technology, DNP Multi-Peer VPN simultaneously enables you to set up an Internet VPN between multiple devices such as smartphones and tablets, without using relay servers.
It not only helps to improve convenience as it supports setting up various types of network, but it also helps to reduce the risk of information leaks in an IoT/IoE society through direct communication with the intended target.

Conventional Internet VPN

  • - Set up a VPN between sites by connecting VPN devices to the Internet.
  • - Requires the purchase of VPN devices and complicated setup. Additional work becomes necessary whenever the network configuration is changed or the number of sites is increased.

DNP Multi-Peer VPN

  • - Communication devices can communicate with each other directly via VPN over the Internet.
  • - No need to setup devices on the communication path. The purchase of hardware at the time of installation is not necessary, either.
  • - Provides SDK for apps and devices with VPN communication features.

Uses of DNP Multi-Peer VPN

DNP Multi-Peer VPN can be used for various purposes by embedding SDK with VPN feature into apps and programs.

1.Enables Simultaneous Multi-Peer P2P Connections

Full mesh P2P connection between devices can be established

After connecting to the server and being authenticated at the start of communication, devices can establish a direct and full mesh P2P(Peer to Peer)connection to each other. Devices can communicate securely with each other via simultaneous multi-peer VPN connection in various situations.

Examples of Use

  • - Confidential P2P call
  • - Online competitive games
  • - Group chat (voice/video)
  • - Simultaneous teleconference between multiple sites
  • - Communication between in-vehicle networks

2.Multi-Factor Authentication
& Unitary Management of Users and Devices Using Management Server

Devices are authenticated by client digital certificate or through original device authentication. Connection setup and update/maintenance, etc. are managed unitarily by Management Server.

3.Supports Various Devices

VPN feature is provided as SDK which is easy to embed into IoT machines and mobile devices, etc.

Supports various OS and devices by embedding SDK

4.Enables Safe & Secure IoT Communication

Various types of P2P network can be established simply.
So it can be possible to collect data from IoT machines to a data server, monitor data from IoT machines by smartphones, and access for updating software of IoT machines from remote place, etc.

5. Affordable VPN Communication & Easy to Set Up

VPN communication can be commenced at low-cost as it doesn't require static IP. Moreover, since it can be used only by entering ID and password following installation, no troublesome setup of access IP address or authentication method is necessary.

6.Existing Network Devices Can Be Used

VPN communication can be commenced using the current and existing routers thanks to the NAT traversal technology.

7.Supports Multimedia Content

DNP Multi-Peer VPN supports bi-directional streaming data such as music and video, as encapsulated packets uses DTLS.

8.Tamper-resistant VPN Client Prevents Malware Infection

When apps with VPN communication features are infected with malware, information may be transferred to malicious servers. If the apps have been protected against tampering, the risk of malware infection is reduced, and even in case of infection the apps cease operation to prevent information leakage.
